    • A packer for a well. The packer comprises a seal element and seal setting apparatus. The seal setting apparatus is moveable with respect to the seal element in a setting direction to apply a setting force to the seal element to move the seal element from a run-in configuration to a set configuration in which, in use, the seal element forms a contact seal with a conduit wall. In use, the packer is arranged such that, in the set configuration, a pressure differential across the packer, which creates a force in the setting direction, will increase the setting force applied by the seal setting apparatus to the seal element to maintain the seal.
    • 一个井的封隔器。 封隔器包括密封元件和密封件设置装置。 密封设定装置能够在设定方向上相对于密封元件移动,以向密封元件施加设定力,以将密封元件从入口构造移动到其中在使用中密封元件形成的设定构型 与导管壁的接触密封。 在使用中,封隔器被布置成使得在设定的构造中,跨越封隔器的在设定方向上产生力的压力差将增加由密封设置装置施加到密封元件的设定力,以保持密封 。
